Pro comp Aluminum heads - Page 3 - Third Generation F-Body Message Boards

thirdgenbird89 · 06-29-2009, 11:49 AM

hey, I am new to this thread but I just bought a pair of procomp pc30035 from white performance and I have been racking my brain trying to get these to work. I have a 305 tpi and after i bought the heads i put them on and the bracket hole in the front of the head is off. than i go to put the lower intake manifold on, there is a gap between the injector hole and the head that goes into the intake runner on the head. wtf? how am i supposed to deal with this? i also bought a set of comp cams roller rockers and the pushrod length is incorect and i guess i need a longer pushrod to run 1.6 ratio rockers

.
when i called and talked to whitesperformance before i bought them and read ALOT of threads on here i was convinced that these were going to be ok for what i wanted to do!!!!!!

yes i had the same problem with the one hole being off too on the passenger side head. i had to drill and tap it . there is about 1.5" of aluminum where the hole goes so you dont need to worry bout hitting the water jacket. you do need the longer pushrods for sure. the remedy for the mismatched ports is the TPIS bigmouth intake or the edelbrock 3860 cast. i bought the TPIS and it covered those big ports easily. call whites and talk to travis and tell him joe serpico said to set you up with the right stuff, he'll take care of you.

youre gonna want the new baseplate anyway because these heads flow like a mofo.

nery nice looking ride. Be careful with that air cleaner tho, had a backfire on my truck and it almost went up in flames..

jag327 · 08-02-2009, 03:54 PM

Only thing air filter I could find that would fit under the hood. 1st start up on youtube

there has got to be better options somewhere. Those are terrible. They start to flake and fall apart, when that happens it just gets sucked into the motor. Plus a good backfire will catch them on fire.

do yourself a favor, toss that air cleaner and get something else.

The only thing I can find that would fit under the hood. Do you no of 1 about this size.

jag327 · 08-04-2009, 03:40 PM

You need plus 100 long than stock, The heads bracket holes was for the older small blocks my mounts bolt right up. Stock is 7.800 you need 7.900 push rods

thirdgenbird89 · 08-06-2009, 06:56 PM

ok well i heard that i needed the longer push rods and the man who sold me the heads also said that i needed longer ones, so i purchased them!? but than when i got the 1.6 rr's they did not bolt on properly. I really think that i may sell them....anybody want a set of pro-comp heads?

91interceptorZ · 08-06-2009, 07:08 PM

I have a set of procomp heads with comp 1.6rr, went on fine..are you using self aligning or not on the rockers (if not you need guide plates)....the heads are okay, but I bought them to have them ported personally. MUCH better after 60hrs of port work (and a lot of money).....

noroxus · 08-07-2009, 03:42 AM

I also have a set of procomps on my 360, never had a pushrod problem, just need to buy +.100 rods.

i never ran them unported, but im running 542hp n/a. so they get the job done.

jag327 · 08-07-2009, 10:53 AM

I'm running roller rockers 1.6 7/16 studs plus 100 push rods butter fly pistons procomp 210cc runners and 58cc chamber, only thing I found that if you use the wrong manifold screws to long the they will hit the push rods in the middle. and my eldelbrock manifold did not cover up a screw hole on the drive side of the motor on toward the front on the heads just glue the hole up. Motor running find making very good power. If you post some pics on how it's sitting on the motor. We may can help you better. At the time I $525.00 for the set. I'm very happy with them. And my friend that has a block 454 40 motor with bigger tires on his car. I cought him in 2nd gear. The little mouse, catching a rat.
