Hopefully you can get your stock rockers to work cause yella terra's are almost another $500 on top of what you just spent for the heads.

We built the PRC 215 heads & 227 heads to use a stock rocker assembly. The bad thing is by the time you buy a $2200 set of TFS heads, upgrade the springs & buy rockers your at closing in on $3000 for a set of heads.

We built the PRC 215 & 227 heads to fit stock long blocks with stock rocker arms if the customer wants to keep costs down. Combine that with the fact that the PRC heads ship with .675" spring standard & you have a unbeatable combo!

I just talked to Shane @ TR and he says it can be done. I'm ordering the shim kit with longer pushrods.

Let us know how it works out for you. Would be cool to know if people can still use factory rockers successfully.

ok i will for sure. i had planned on going to the dyno fri night and getting the tune lined out on this thing, but i stumbled upon a set of heads so its gonna be another week or so. im just ready to get to the track and see what this thing will do

just got my heads in today. ordered my shim kit / pushrods a while back and am still waiting so i cant put these on yet but here they are.

ok all the rest of the parts i needed for this swap should FINALLY be here this week and hopefully me and my dad can get these on. Any advice or pointers you guys have to make this go as smoothly as possible?

also what head gaskets and bolts should i use. gm gaskets and new factory bolts be ok??? arp is high dollar and id feel like and idiot paying that for bolts.

SSmoken

iTrader: (26)

should the head bolts be able to be broken loose very easily? like with one hand on the socket? figured theyd be alot tighter than this.

The head bolts should be tighter, they were when i did my heads!!! As for your question before, i just went with the GM MLS gaskets and stock bolts, if your on a budget they should be fine

i had to use a breaker bar on all of mine and stock headgaskets work just fine, same with brand new stock headbolts . . . once those things are torqued they are done. good luck!

SSmoken

thats odd. none of mine where really that tight except for the bottom 5 bolts. pretty sure they have never been off before either. ok cool cause i went with mls gaskets and stock bolts too. heads are on the motor. just need bolted down, rockers attached and everything else put back together. thanks for the input fellas

Any chance the heads your taking off are warped?

SSmoken

iTrader: (26)

i wouldnt think so. i mean they were tight, just not breaker bar tight. how can you tell if they are warped?

done for today. spark plugs, tb, and valve covers need put on tomorrow. then she will be fired up. i sure hope everything is right and there are no issues.

BaddBird

You can check for warp with a straight edge and a feeler gauge. I ask because I see that allot on heads that are warped some head bolts tighter then others.

Nice progress, I am looking forward to your dyno numbers once everything is done. I am running El Toro too with 243s and I know you will put down some great results with those heads there.

umm there is nothing idiotic about them.. they are reusable unlike GM bolts.. those are TTY.. so next time you pull yours heads off you won't have to buy new bolts.. thats not idiotic

SSmoken

ok cool. ill check it out.


as long as it breaks 400hp (mustang dyno) ill be happy.


i realize that, but im on a budget. if you have the money then go for it. im not calling anyone else names. just saying thats what id feel like if i spent that kind of money on bolts being in my situation. however i dont PLAN on taking these heads off.......EVER lol.
