i know everyone says they suck but i have never heard why? i read the thing about the hci that only gained 50 horse but that seemed to lack facts. im not trying to start a thread war im just curious

 

valvetrain geometry, thin valve cover rail, pushrod pinch area, 110% junk valvetrain if bought for 800 dollars assembled, they are 220 dollars per piece bare for dealers, so between as good valve job, good valves, springs, locks, retainers, seal, guideplates, rocker studs. What do you think you are getting for 800?

 

makes sense im buyin canfeilds but i have always wondered y procomps were so hated

 

I'd look into AFR'S or trick flows.

 

besides poor quality parts theres the whole, total lack of hp gain to go with them

 

You may see a 50 hp gain at peak hp with a set but they flow like crap down low. The flow numbers are very erratic from port to port and the flow sucks at low lift and I've already seen two of them with the valve seats burried in them. They are better suited to a budget drag car.

 

for $800 youd be better off with X303 heads or "GT40X" they are called.


or just save a bit longer for trickflow/afr's

 

im not planing on running procomps, i already most of my motor planned out except for injectors, maf and TB. im gonna run canfeild heads, i was just curious as to y procomps had a bad name

 

I have the Floo Tek brand, and I keep hearing them referred to as ProComp heads. I have seen so many postings, I don't know who to believe. I bought them from MoneyMaker who builds engines and races. He has a good rep. He swore by them for entry level and better than GT40 heads. Told me they were casted in Australia. Now his site links to TCHS, which is the name on the box, I got my heads from. Here is a pic in the bag. BTW the valve cover rails do not look thin to me. Have not installed them or unbagged them. They look decent and were totally finished including valves and springs and multi angle valve job. Check out MoneyMaker's website. He will answer all questions and emails himself.

 

i have a set that was never ran if you want to find out.
