My heads are heavily ported(especially now) iron Windsor Jr's with Manley pro flo valves. The angle mill is done and I have to go pick them up. They cut .060 off which should bring my compression up to where my cam has always expected which is around 10.5:1. They said they have everything done straight and true for the angle cut. I'm hoping for good things out of all this work. A little less valve angle will help, my porting should definitely help and the increase in compression will definitely help. The big question is how much. My last series of runs earlier this year was in the 12.20's. The car ran 11.72 best with the interior gutted but I have added a significant amount of weight with convert torque boxes, full interior back in and sub frame connetors. My valve springs got tired and it was falling over on the top end which is what started all this head work. It would be nice to be back into the 11.70's. I'm switching to a bunch of fiberglass body parts like bumpers, hood and deck lid to see if I might balance the weight out. I might pull one of the 2 batteries I have in the trunk also.
My guide plates seemed odd because all the new ones I see are smaller and the actual guides are above the plate so they are 2 dimensional or 2 step types. Mine have worked for several years though. Is there any particular advantage in these compared to the Manley ones I have;
I need new studs and new roller rockers so going to 7/16th's would not be any extra cost. They appear to cost about the same. 3/8ths would probably still work fine since that is what I've been running for years but sometimes you can't see what the difference in stud size is doing to your valve train.
That was the Trick Flow rockers I was looking at. They concerned me because they almost seem to be too cheap compared to the other rocker prices. I like the looks of those Comp ultra pro magnums though. Chrome moly, lighter than aluminum and they have a smaller profile to boot which should prevent interference problems.
I'm running .560 lift and all the roller rockers I've looked at that are above cast level should handle my lift and spring sizes with no problem.
Sorry I am asking so many questions on this. Screwing something up in the valve train is something I really need to avoid.
Depending on the amount of degrees the shop cut I may or may not need new push rods. That will just have to be checked but if I do its no problem.
