I wouldn't worry about compression right now. stock is enough for a mild cam.

get rid of those heads!

do a stock vortec top end swap, add a little more cam, headers, and dual 2-1/2 exhaust.

im trying to keep this motor "tbi", if i add any more cam the tbi will not run rite, without chip and all that complicated stuff, i just want more than factory 190-200hp, like 300hp, i have the summit k1102 cam 420"/442", 204/214 262*/272*, thats a good RV, 4wd, towing cam, now im prb looking at some D-shaped dish pistons with +11-12.00 head volume, witch would get me 9.1:1-9.3:1cr depending on head gaskets, i would norm i would use .039 felpro's peratorq's, ill ether use thoughs or some .028's if i can get some for a good deal... also thinking about porting the stock heads to get it reving better too, going vortec can get expesive like used heads here are $125 each, then 85% of the time they need work done, the new one are like $650-700, then a Gmpp intake for the tbi is like $400 so im looking at $1000, just to do the top end, now to port it i could get done for cheap, im reuseing the stock intake and trottle body, yeah headers im looking at too, i dont know how much HP this will get but im hopeing 250-300hp range..... now b4 i go the vortec rout, id be closer gooing carb, with older heads??

heck i may go ahead and use a flattop with +6.00 head volume, with uncut deck and a .039 head gasket id be in the range of 9.3:1-9.6:1, that looks like a good deal too?????
