Paul pistons are new Q-16's and should have adequate room..... Of course I would check it but they build those pistons with plenty of notch depth. I know I have plenty of P-V clearance with the R-M cam and I have 1.75 rockers on both I&E..... The CC 729 intake lobe was .497 instead of .484 on the CC 719.. .847 Gross lift - the lash on the 719 w/1.75's Actual lift about .820's .869 Gross lift - the lash on the 729 w/1.75's Actual lift about .840's Keeping lift at .850 or under works with my springs....I've used both PAC's and PSI's.....both work with zero issues... My R-M cam is a .475 intake lobe and a .450 exhaust....IIRC... So P-V will definitely get tighter.... | |||

Originally posted by SCDIV1: Biggest gain I saw on this engine was going from a Brodix intake to the SV565....Picked up a solid 1-2 MPH. "Rich, tell us more about this". Ed I had a Brodix Intake and it was port matched to my heads by me of course....I forget the part number but it is a low deck intake that fits any -3 Oval head. I have to just skip forward to when the SV's came out and I read numerous posts by racers and engine guys saying they picked up 1-2 MPH going to the SV's I was concerned about it fitting my heads..... Bill C. had offered to lend me one to trial fit but I took a chance and just bought one... It fit well, needed some port match work but no big deal... I immediately saw 1-2 MPH running S/C and it was no BS..... I have run more MPH with that intake and a plate stop vs an inline stop or Dedenbaer slide stop which has no restriction when open.... My best ever was 176+ with an under carb plate and I probably never ran better than 174 with an inline stop and the Brodix.... That was my experince.....I sold the Brodix intake..... I've told others but not everyone sees the same gain I did....... I use Cometic intake gaskets and they offer them in thicker versions which for me was needed to get the ports better aligned..... | |||

was this on gas? sounds like it's worth a try if I don't build a new engine for this coming season. I would be using the tall deck version. | |||

Yes on gas and I've been using the same QF 1050 carb since 2014 I did play with Q-15 for a while and it is faster but I could not stand the fumes....Hideous stuff.... I still have some and ran it in my snow-blower last snow storm....I was buzzed just blowing snow from the fumes.....! I run Sunoco Red or X-16 as my preferred 2 fuels. | |||

Excellent information. When it comes to cams I have used Comp Cams custom grinds primarily and always stressed to them one or two mph wasn't worth sacrificing valve spring life for. Cars always performed like I expected but the set of PAC springs on the Profilers is going in to their 5th season, about 450 runs and check out great. In 10 round races I do not want to be checking valve springs or just throwing new ones on "because they probably need it". Just a budget consideration really. Good info though, thanks! Jok | |||

Biggest lie in the business. Big springs = better valve control. I ran titanium valves and with that cam and T&D shaft rockers. Erson 915170 set for 280# on the seat. They refused to fail and was gentle on everything. https://youtu.be/VCKVPIdVebo 2005 2000lb 4 link dragster home brew 582 BBC Dart 355 1.058 2.98 4.629@149 6.094 7.310@185 | |||

Yes I agree to he extent that a happy driver is gonna be on top of his game when happy. Good Luck Paul. Just for info only, I know of a division driver that runs gas on his ride. I asked him about it and he quoted that it took him years to get there. He didn't tell me his tuneup but did offer this: Practice, Practice, and practice. Stop changing on what you hear from the forums. Stay patience he said. One thing at a time. If I told you his name, he said that he would put me out first round. On gas his combo is deadly consistent. No don't ask me his name. I wanted the answer right away. He said just put the time and effort into it and then you'll understand. Oh well. Ive known this guy for over 25 years. Good Luck folks | |||

Steel valves....same pressure on the seat and never have any evidence of valve float when I take heads apart.....never hurt a lifter or a rocker or pushrod....7400 usually at the stripe.... Jesel Sportsman rocker system...... Pac or PSI 1224 springs.....Never lose pressure and never broke one of either brand..... I have seen spring breakage with blue stripe Nexteks, same size and pressure spring. Won't use 'em... | |||

Thanks everyone for the feed back on this. Now just have to get some head gaskets ordered and lash caps ordered. Whats everyone running/using for lash caps and head gaskets these days? The I have some manley caps and felpro 1077041 gasketes in the shop. Was thinking of using them. | |||

Manley caps and cometic gaskets | |||
|
| DRR S/Pro |
Cometics and I also use Cometic intakes because they will not fail and they offer them in various thicknesses if needed.... I don't use lash caps.....But yes Manley parts are fine...This message has been edited. Last edited by: SCDIV1, | |||

Like Ed said, Cometics for the head gaskets. Keeping the Socialists and NEO-LIBERALS at bay with FACTS one post at a time !!! Freedom isn't free !!! Thank a veteran, they will actually appreciate it. | |||

Anyone able to Cross Reference the FelPro 1077041 with Cometic | |||

When using Cometic make sure to follow surface finish guidelines. They make a great product. BG | |||

I’ve always felt that lash caps do way more then protect the valve tip on some valves like titanium. They also provide stability with a wider landing pad for the rocker tip as it closes the lash and meets the spring pressure. Can it be measured? Probably not, but I’ve also been a believer that little betterments add up and do make a difference, like belt drives and shaft rockers. 2005 2000lb 4 link dragster home brew 582 BBC Dart 355 1.058 2.98 4.629@149 6.094 7.310@185 | |||
